Being interested in music, after a few years he was able to learn music with Abolhassan Saba, who started teaching him to play the violin, without charge. After spending a period of notation and familiarity with the steps and technics of Iranian and Western music, Saba suggested teaching him how to make violins. He and Saba he went to meet Soren Araklyan, a Russian immigrant and the author of Monverni, and learn his ideas and his research about music. Araklyan introduced Ganbari to the head of the Fine Arts Department, who offered him paid employment. After a year Saba died.

Russian violist David Fyodorovich Oistrakh visited the workshop, and Ibrahim Ganbari asked Walto if he could let Oistrakh play his violin; his opinion was:

"Congratulations for your eagerness, talent and perseverance which has been put into your extraordinary made violin, I've seen such a perfect instrument which has the qualities together.
I wish you great success in the future"
Sincerely yours,
David Oistrakh
